@doug Hey Doug, I see your issue with going from design tools to XCode. I had a look for some alternatives and came across a tool called Yotako - I actually met Alfonso who made the app before and had a demo of it back in August.
This might be late notice, but he has a demo of it starting in about 20 minutes. Here's a link: https://my.demio.com/ref/O5BWNvqBneX3Vnuu
Hopefully it will be recorded for those tha can't see it, but I'll report back on what I learn

@Graeme I found this article on Try Design Thinking + Scrum quite helpful for integrating design with the development lifecycle. It highlights the importance of combining design thinking (empathize, define, ideate, prototype, test) phases with iterative agile Scrum sprint builds (backlog, plan, review, retrospective). It also mentions user story mapping as a useful technique for establishing a feature backlog.
